General; Function; Self-Test - TESTBOY Profi III LED Bedienungsanleitung

Operation
| Correct indication is ensured in the tempera-
ture range of −10 °C
| Always keep the device dry and clean. The
housing can be cleaned using a moist cloth.
| The additional warning symbol, acoustic indi-
cations and vibration for voltages > 35 V are
only for warning of hazardous voltages, not
for measurement.
| Before the test, check the audibility of the
warning sound at the ambient volume.
| Immediately replace the batteries when a con-
tinuous warning signal sounds when switching
on.

General

Voltages have priority. If no voltage is applied at the measuring probes
(< 3 V), the device is in the continuous test mode. In stand-by mode, the or-
ange "Rx/" illuminates.

Function

To switch on the device, simply hold the test probes on one another.
Attaching and removing the measuring probe adapter makes it easier to car-
ry out measurements at the socket.
Indication of the voltage is carried out without the batteries.

Self-test

For the test, keep the probes apart. The green "Rx/" LED must clearly illu-
minate and a beep tone sounds. (After a short period, the device automati-
cally switches off by the "Auto Power Off" function.) If the LED does not illu-
minate, or only faintly illuminates, replace the batteries.
If the device does not function with the new batteries, it must be protected
from misuse.
